In October 2010, Apple released the 2nd generation MacBook Air. The redesigned notebook is available in 11-inch and 13-inch models. We cracked open the 1st generation MacBook Air (released in 2008) and could wait to get our hands on the 2010 model.

Follow along as we crack open the 11-inch MacBook Air.

To disassemble the new Air you'll need a screwdriver with Torx T5 and T9 bits and either a very small flathead screwdriver or special "cloverleaf" security bit.

The 2010 MacBook Air is available in four basic configurations--11-inch with 64GB of storage, 11-inch with 128GB of storage, 13-inch with 128GB of storage, and 13-inch with 256GB of storage. Within each of these divisions, you can further customize the processor and RAM.

We purchased both an 11-inch and 13-inch MacBook Air. In this photo, the smaller Air is sitting on the larger.

In the box, you'll find the MacBook Air, 45W MagSafe power adapter, power cord, product documentation, and software reinstall drive.

The new MackBook Air's 45W MagSafe power adapter is the same size as the power adapter on the 2008 MacBook Air.

A long-overdue feature, this USB drive lets you reinstall the versions of OS X and iLife that ship with the MacBook Air.

The 11-inch MacBook Air starts at $999, and I thought it would be interesting to compare it to another 11-inch notebook that costs $999--the Alienware M11x.

We reviewed the Alienware M11x back in April. As of this writing, an M11x with an Intel Core i5 520UM, NVIDIA NGT335M GeForce GPU, 4GB SDRAM, and 500GB HDD.

From the top, both 11-inch notebooks are about the same size.

When you look at the sides of each notebook, the MacBook Air's thinner profile is immediately noticeable. The Alienware M11x may have more power than the Air, but Apple's ultra-thin machine is definitely more portable.

Although the MacBook Air's case screws are easily accessible on the bottom panel, Apple used 5-point, tamper-resistant Torx screws.

It took a bit of work, but I was able to remove all 10 case screws with a small slotted screwdriver. While I slightly damaged a few of the screw heads, I should be able to put them back in. If you're going to work on the new MacBook Air, I recommend getting a screwdriver specifically made for this type of screw.

Eight of the case screws are very short and two (along the back edge) are longer.

With the bottom panel removed, we get our fist look at the MacBook Air's internal hardware. The large battery assembly takes up the vast majority of room inside the case. Above the battery, is the main logic board, cooling fan, wireless card, and SSD storage unit.

The 2010 MacBook Air uses flash storage, exclusively. Our test unit came with 64GB. A single Torx T5 screws holds the unit in place. Once the screws is removed, you can disconnect the unit from the main logic board.

Next, I'll remove the cooling fan, which is held in place by three Torx T5 screws that I've already removed.

Before lifting the MacBook Air's cooling fan away from the main logic board, you'll need to disconnect both ends of a thin, black ribbon cable, which runs across the fan and is stuck to the fan housing.

While you're disconnecting the ribbon cable that runs across the fan, you might as well disconnect the left-side speaker cable underneath.

You can also detach the connector that attaches the small, left-side circuit board to the main logic board. This smaller board contains the MagSafe power port, one of the unit's two USB ports, and the headphone jack.

With all the screws removed, and the cables disconnected, you can lift the cooling fan away from the main logic board.

Before lifting the main logic board away from the MacBook Air's case, we need to disconnect the display cable.

The display cable requires a fair amount of force to pull free of its connector, but luckily it has a small handle to pull on. With this cable separated from its connector, we can lift the logic board away from the case.

The top of the main logic board contains three main components of the MacBook Air--the Intel Core 2 Duo CPU and NVIDIA GeForce 320M GPU (covered by the heat sink) and Elpida RAM chips.

We'll need to clean the thermal paste from the CPU and GPU for a clear look at the chips.

With the thermal paste cleaned off, we can clearly see the marking on the MacBook Air's NVIDIA GeForce 320M graphics processor.

There are no visible marking on the core of our MacBook Air's Intel Core 2 Duo 1.4 GHz CPU, but there are markings printed onto the chip's green circuit board.?

Our MacBook Air came with 2GB of 1066MHz DDR3 SDRAM. Like the previous MacBook Air, the RAM is soldered to the main logic board. Upgrading the Air's RAM after purchase isn't possible. As the upgrade from 2GB to 4GB is only $100, I recommend going with the 4GB.

After working our way around the MacBook Air's main logic board, we should turn our attention back to the case. A small circuit board is located on the case's left side and contains the MagSafe power port, USB port, and headphone jack. Three cables connect it to components remaining in the case. You'll need to disconnect all of them before lifting the small board away from the case.

Several thin adhesive strips hold the MacBook Air's antenna wire to the case. The strips run through think slots in the case and are folder over the cable. You'll need to pull the strips through the slots and pull the wire free from the case before removing the lid.

While the 2010 MacBook Air isn't difficult to disassemble--tamper resistant case screws aside. Nearly all of the internal components are proprietary. It's unlikely that many IT pros, let alone the average consumer, will ever upgrade the RAM or replace the flash storage unit.
